The Lowdown

Alright, let’s get into it. The next couple of weeks are looking like a proper mix of flat spells and some solid, powerful windows. The first few days are pretty quiet, nothing worth paddling out for until Wednesday morning. There’s a real gap at the start, so don’t rush to the beach on Monday or Tuesday.

The first real push of energy hits Wednesday morning (August 5th) with a new south swell. Jaconé (Costa Rica) sees clean 3ft waves with that offshore breeze making things tidy. The swell energy is moderate at 646, and the water’s sitting at 73°, which is right about average for this time of year. It’s a decent start, but nothing that’s going to blow your wetsuit off.

Thursday and Friday keep things small and a bit jumbled, with short-period ENE windswell. The waves are there on Thursday morning at 5ft, but the period is only 7 seconds, so it’s going to be a bit lumpy and disorganized. Friday morning is similar, around 4ft, but still short-period. It’s surfable, but you'll be hunting for the clean ones.

Then things start to get interesting. Saturday afternoon (August 8th) sees a jump in size and period, with a new SSW groundswell filling in. The energy is strong at 1145, but the wind is a bit tricky, making it a so-so session. The real standout is Sunday morning (August 9th). We’ve got 7ft of SSW swell with a 14-second period, and the energy is cranking at 1611. The wind is light and cross-off, leaving it clean. This is a proper groundswell, and it's a big one, so it’s for experienced surfers only. This is the day to circle on the calendar for the first week. The water temp is still normal, but that swell is the story.

The start of the following week keeps the swell going, but the wind becomes a constant battle. Monday and Tuesday are a mix of onshore and cross-onshore winds, making the conditions messy, even though the size holds around 6ft to 7ft. It’s not pretty. You’ll see the energy readings stay high, but you’ll be surfing chop.

We get a brief reprieve on Wednesday morning (August 12th) with lighter winds and clean 6ft waves. That’s a good one. Thursday morning is also worth a look, with 4ft of clean SSW swell and a 13-second period. The energy is still solid, and the morning glass-off is a real positive.

Then the model throws a curveball. The weekend of August 15-16 is where the real muscle shows up. Saturday afternoon (August 15th) looks incredible – solid 6ft of clean SSW groundswell with a 14-second period and light offshore winds. The energy is pumping at 1259, and it’s a standout for sure. Sunday morning (August 16th) pushes even bigger, with 7ft of S swell, but the wind is howling offshore at 30 km/h. That’s going to be a serious, heavy, and powerful session – again, experts only. The energy is right up there at 1565. This is the second-week window to keep an eye on, but it's a long-range call, so take it with a grain of salt.

After that, the size drops back a touch for the final few days. Monday and Tuesday (August 17-18) have clean 5ft waves with good winds, but the energy is starting to fade. Then Wednesday morning (August 19th) is another sneaky good one – 4ft of clean SSE groundswell with a long 14-second period and glassy conditions. It’s not the biggest, but it’ll be lined-up and perfect.

So, the true standouts are Sunday morning August 9th and Saturday afternoon August 15th. Big, clean, powerful south swells. If you can only surf one or two days in this stretch, those are your best bets. The rest is a mix of workable and messy, so pick your moments.

Rusty.

Information about the Jaconé Surf forecast

The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.

Jacone is 14 km (9 miles) from the city of Saquarema. If you plan a holiday in Rio de Janeiro, look for hotels and other accommodation in Saquarema. Saquarema has rooms for a wide range of budgets as well as car hire and transport links.
